Some 13,300 chocolate Easter bunnies distributed to schools and other fund-raising groups were recalled in 15 states, including Utah, because of approximately half a dozen complaints about glass or similar objects found in the candy, company officials said Thursday.

New Jersey authorities said testing confirmed a sliver of glass was embedded in one piece of the candy made by Scott's of Wisconsin that was turned over to state officials for testing. No injuries were reported.The authorities in New Jersey said product tampering was not suspected and a problem at the manufacturing plant probably was to blame. Officials of Scott's of Wisconsin said they had not determined an exact cause.

Scott's of Wisconsin said it voluntarily recalled Wednesday four lots of its "Krispy Kids & Mom" rabbit-shaped candy in the 4-ounce size.
